Description
1. Field of the Invention
The present invention relates to an aqueous built liquid detergent composition. More particularly it relates to an improvement in the storage stability of aqueous built liquid detergent compositions, obtained by the inclusion of a particular hydrotrope system therein.
2. Description of the Prior Art
It is well known that aqueous built liquid detergent compositions may suffer from storage instability leading to phase-separation, both at room temperature and at temperatures below 0° C., if no proper precautions have been taken. Furthermore, aqueous built liquid detergent compositions are normally required to be homogeneous, clear liquids, which also demands special precautions.
One of the common practices to achieve stable, homogeneous, clear liquids is to incorporate hydrotropes in aqueous built liquid detergent compositions, which solubilize particular ingredients in the liquid compositions. Commonly employed for said purpose are hydrotropes such as urea, ethyl-alcohol, toluene-, cumene- and xylene sulphonates. However, whereas such hydrotropes may give the desired effects, the amount required may be rather high, or, with particular aqueous built liquid detergent compositions, they may not produce the required degree of homogeneity, clarity and storage stability.
It has now been found that a hydrotrope system comprising a sulphonate-type hydrotrope of the general formula ##STR1## in which R is a methyl, dimethyl or isopropyl residue and M═H, NH4, substituted NH4, or an alkali metal, such as sodium or potassium, and an alkane phosphonic acid of the general formula ##STR2## in which R is a saturated alkyl residue with 4-10 carbon atoms, and M is H, NH4, substituted NH4 or an alkali metal such as sodium or potassium, significantly improves the homogeneity, clarity and storage stability of built aqueous liquid detergents.
In comparison with the sulphonate-type hydrotropes alone, the combination enables a significant reduction of the amount of sulphonate-type hydrotrope used, while simultaneously improving the overall hydrotrope effect, and vice versa with regard to the alkane-phosphonic acid alone.
The sulphonate-type hydrotropes are toluene-, xylene- and cumene sulphonates, preferably in the form of the sodium salts, although potassium, ammonium and substituted ammonium salts may also be used if desired. Particularly preferred are sodium toluene- and xylene sulphonate.
The other hydrotrope is a monoalkane phosphonic acid, in which the alkane residue may be branched-, but is preferably straight-chained, and contains from 4-10 carbon atoms. It may be used in the acid form, or in the form of the mono- or dialkali metal metal such as sodium or potassium, ammonium and substituted ammonium salt. Particularly preferred is monooctane phosphonic acid.
The amount of the sulphonate-type hydrotrope used in the present invention is from 0.75-8.5% by weight of the composition, and the amount of monoalkane phosphonic acid is from 0.5-2.5%, preferably 1-2% by weight of the composition, with the proviso that in the case of sodium xylene sulphonate more than 4% thereof should be used if the amount of monoalkane phosphonic acid is 1% or less. The hydrotrope system provides for better stability, clarity and homogeneity when included in aqueous built liquid detergent compositions, i.e. compositions containing an active synthetic detergent composition and an inorganic builder salt. Such builder salts include the sodium or potassium ortho-, pyro- and polyphosphates, and sodium or potassium carbonates, and mixtures thereof.
The benefit of the invention is particularly achieved in aqueous liquid detergent compositions which contain alkali metal carbonates such as sodium or potassium carbonate as the builder salt. The amount of the inorganic builder salt present in such liquids may vary from 1-25% by weight, and preferably lies between 5 and 15% by weight.
In carbonate-built liquid detergents it is useful to include a polyelectrolyte to prevent undesired incrustation or soil redeposition. Such polyelectrolytes are e.g. polyacrylates, copolymers or ethylene with maleic anhydride or copolymers of maleic anhydride with vinylmethylether. Particularly preferred are polyacrylic acids with a molecular weight of between 3,500-22,000. The amount of polyelectrolyte used varies from 0.5-5%, preferably from 1-3% by weight.
Although the liquid detergent compositions may comprise a simple synthetic detergent active such as an alkylaryl sulphonate with 10-24 carbon atoms in the alkyl chain, an alkane sulphonate with 10-24 carbon atoms in the alkane chain, alkylether sulphates with 10-24 carbon atoms in the alkyl chain and from 1-10 moles of an alkylene oxide such as ethylene oxide and/or propylene oxide, nonionic synthetic detergents i.e. adducts of 5-30 moles of an alkylene oxide to a C10 -C24 primary or secondary alcohol, to a C9 -C18 alkylphenol, soaps, amphoteric surfactants etc, it has been found that the benefits of the invention are particularly obtained in an aqueous built liquid detergent composition which comprises a ternary system of detergent active materials, i.e. an anionic + a nonionic + a soap. The anionic synthetic detergent is a C10 -C24 alkylbenzene sulphonate (as alkali metal, e.g. sodium or potassium, ammonium or substituted ammonium salt), the nonionic is an ethoxylated linear C8 -C22 alcohol condensed with 3 to 25 moles of ethylene oxide and the soap is a sodium or potassium, ammonium or substituted ammonium salt of a polymeric fatty acid, predominantly consisting of dimerized oleic acid. The amounts of the anionic, nonionic and soap may vary from 5-15, 1-5 and 1-5% respectively. Other anionics, nonionics and soaps, including soaps of C10 -C24 fatty acids may also be used instead of the above-identified ones.
The compositions may furthermore comprise the usual ingredients such as silicates, borates, phosphates, fluorescers, soil-suspending agents, lather controllers or lather boosters, perfumes, germicides, enzymes, opacifiers, anti-redeposition agents, and so on.
The invention will now be further illustrated by the following Examples.

First a premix of the potassium hydroxide, the dodecylbenzene sulphonic acid, the dimerized oleic acid, and the C13 -C15 primary alcohol condensed with 11 moles of ethylene oxide was prepared, to which subsequently the remaining ingredients were added under agitation, and without heating. The amount of sodium xylene sulphonate (x) and monooctane phosphonic acid (y) were varied in a series of experiments, and the physical characteristics of the liquids obtained were assessed.

______________________________________
This example shows that monooctane phosphonic acid alone did not produce a clear, homogeneous liquid, and that only with 18-20% sodium xylene sulphonate (40.7% active material) alone a clear, homogeneous liquid both at room temperature and at -4° C. could be obtained. The combination of these two hydrotropes with e.g. 10% of sodium xylene sulphonate (40.7% active material) and 1% monooctane phosphonic acid produced already a clear, homogeneous liquid, i.e. a reduction of the sodium xylene sulphonate by almost 50% could be obtained.

______________________________________
Varying amounts of x, y and z were used (x = 0-30%, y = 0-30%, z = 0-3%), and the liquids were stored at room temperature, and at changing temperatures (-4° C. and room temperature) 5 times, each for 48 hours. The products were assessed for clarity, homogeneity and stability, they being found satisfactory if the liquid was clear and homogeneous, or, in the case of the changing temperatures, if there were crystals which rapidly dissolved again or when there was only a temporary cloudiness.
The following results were obtained:
______________________________________
Liquid A was satisfactory when
x = 10-20%
z = 1%
or y = 2-10%
z = 2%
Liquid B was satisfactory when
x = 12-14%
z = 1%
or x = 2-10% - z = 2%
or y = 10-12%
z = 1%
or y = 2-6%
z = 2%.
______________________________________
In all other cases, using x or y or z alone much more was needed to obtain satisfactory liquids, e.g. for liquid A either x = 22-30% or z = 3% was needed, and with y alone no clear liquid was obtained at all. For liquid B, neither x alone nor y alone nor z alone produced a clear liquid.
